Network Cable Synergy 21 Patch Cable RJ45 CAT8.1 2000Mhz Grey S-STP S/FTP TPE/LSZH SuperFlex S218143

The Synergy 21 Patch Cable RJ45 CAT8.1 2000MHz Grey S-STP S/FTP TPE/LSZH SuperFlex S218143 is a high-frequency network cable designed for demanding Ethernet environments. Engineered to support data rates and signaling at frequencies up to 2000 MHz, this CAT8.1 patch cable uses a screened shielded twisted pair (S-STP) with overall S/FTP shielding to reduce electromagnetic interference and crosstalk. The jacket and insulation combine thermoplastic elastomer (TPE) and low-smoke, zero-halogen (LSZH) compounds to deliver enhanced flexibility and improved safety in confined or poorly ventilated spaces.

Advantages

This CAT8.1 patch cable offers superior noise rejection through its S-STP and S/FTP shielding configuration, helping maintain signal integrity in electrically noisy installations. The 2000 MHz rating enables high-throughput applications and future-proof connectivity for high-bandwidth networks. TPE/LSZH construction provides a balance of flexibility and reduced toxic emissions in case of fire, while the SuperFlex design improves cable routing and handling in patch panels and dense racks.

Suitable for

• Data center uplinks and switch-to-switch connections
• High-speed backbone and server interconnects
• Professional AV over IP systems and broadcast facilities
• Office networks requiring shielded cabling to reduce interference
• Environments where low-smoke, zero-halogen materials are required

How to use

Install the cable by terminating each end with compatible RJ45 connectors and ensuring proper grounding of the shield to maintain shielding effectiveness. Route the cable through cable management paths, avoiding sharp bends and sources of mechanical stress. For best performance, keep patch lengths within recommended limits for high-frequency links and avoid untwisting pairs beyond the connector termination point. Verify link speed and signal integrity using appropriate network test equipment after installation.

Usage recommendations

For optimal results in high-density or electrically noisy environments, use shielded connectors and ensure continuous grounding of shields at patch panels and equipment chassis. When deploying in public or enclosed spaces, the LSZH jacket reduces harmful emissions in case of fire. Inspect cable bends and connectors regularly in active installations to maintain reliable high-speed performance.
